[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] The embodiment of the utility model discloses a high-definition camera device for public safety.

[0027] The utility model provides Figure 1-3 The high-definition camera device for public security shown in the figure includes a base 1 and a rotating column 2 rotatably arranged on the top of the base 1, a support column 3 is fixedly provided on the top of the rotating column 2, and two symmetrically arranged vertical slots 4 are provided on the outer wall of the support column 3, and two symmetrically arranged transmission holes 5 are provided between the two vertical slots 4 and the support column 3, and the connecting parts of the vertical slots 4 and the transmission holes 5 are chamfered, and a transmission belt 6 is passed through the multiple vertical slots 4 and the transmission holes 5 for transmission, and a camera 7 is fixedly provided on the outer wall of the transmission belt 6, a through hole is provided inside the base 1, the lower end of the rotating column 2 is arranged in the through hole, and an angle adjustment mechanism is provided, the angle adjustment mechanism includes a worm gear 9 and a worm 10, the worm gear 9 is fixedly sleeved on the outer lower end of the rotating column 2, the worm 10 is rotatably arranged in the through hole and is cooperated with the worm gear 9, the end of the worm 10 passes through the base 1 and extends to the outside, and is fixed with a crank 11.

[0028] When the camera 7 is in use, when the lateral shooting angle of the camera 7 needs to be adjusted, the crank 11 can be turned to rotate the worm 10. Since the worm 10 can cooperate with the worm wheel 9, the worm 10 can drive the worm wheel 9 to rotate and drive the rotating column 2 to rotate, so that the rotating column 2 drives the support column 3 to rotate under the support of the base 1. At this time, the support column 3 can drive the camera 7 on its outside to rotate horizontally, thereby completing the adjustment of the lateral shooting angle of the camera 7. Since the worm wheel engagement is self-locking, the camera 7 can remain stable after the position is adjusted.

[0029] In order to be able to adjust the shooting height of the camera 7 conveniently and to facilitate the camera 7 to be quickly removed for maintenance, Figure 1 and Figure 3 As shown, a plurality of spaced positioning holes 8 are provided inside the transmission belt 6, a through slot is provided at the lower end of the support column 3, and a height adjustment mechanism for limiting the position of the transmission belt 6 is provided between the through slot and the positioning hole 8. The height adjustment mechanism includes a positioning rod 12, which is slidably passed through the upper end of the through slot, and the end portion is inserted into the positioning hole 8. A guide plate 13 is fixedly provided at the lower end of the positioning rod 12, and guide slots 14 are provided on both sides of the inner wall of the through slot. The end portion of the guide plate 13 is slidably provided in the guide slot 14, and a spring 15 is fixed between the guide plate 13 and the inner wall of the guide slot 14. A pull plate 16 is fixedly sleeved on the lower end of the positioning rod 12, and the end portion of the pull plate 16 passes through the support column 3 and extends to the outside.

[0030] Through the connection of the transmission hole 5 and the vertical slot 4, the transmission belt 6 can be transmitted inside the support column 3. At this time, through the connection of the transmission belt 6, the shooting height of the camera 7 can be accurately adjusted. At the same time, under the insertion of the positioning rod 12 and the positioning hole 8, the setting of the transmission belt 6 can be ensured to be stable and firm, thereby fixing the use position of the camera 7. When the transmission belt 6 needs to be rotated and the camera 7 needs to be removed, the pull plate 16 can be used to drive the guide plate 13 to move downward, so that the guide plate 13 squeezes the spring 15 under the sliding limit of the guide groove 14, and pulls the positioning rod 12 out of the positioning hole 8. At this time, the transmission belt 6 is not restricted and can perform transmission work. After the position of the camera 7 is adjusted, the pull plate 16 is released. Under the elastic force of the spring 15, the guide plate 13 pushes the positioning rod 12 to be inserted into the positioning hole 8, and the position fixation of the transmission belt 6 and the camera 7 is completed again.

[0031] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
